Patented Dec. 6. 1910.

Application filed December 11, 19(18. Serial No. 266.998.

To all whom it may concern:

- Be it known that I, \VILLiAu- C. (Link, a

citizen of the United States, residing at Bufi'alo, in the county of Erie and State of car but are also connected to a source of electric power and actas a conducting me-- New York, have invented a certain new and I The rails are preferably of channel form 111 cross section with the groove or channel on the under surface of the rails, see

useful Improvement in Transportation Systens, of which the following is a specification. 1

This invention relates to a transportation 'scries ot individual boxesD for mall or system, and the object of the invention is to simplify and improve systems of this class, to provide a strong and durable construction, and to, insure certainty of operation.

The invention also relates to certain details of, construction which will be hereinerence being had to the accompanying drawings whlch an adaptation of the invention is illustrated.

- Figure 1 represents a. side elevation of a fragment of an elevated track with a car supported thereby, and also showing a side Iv view of a fragment of one of the supporting I view of a car supported thereby and also standards. Fig. 2 is a transverse section through the rails of a track with an end showing a side'view of a fragment of one ofthe supporting standards. Fig. 3 is an enlarged vertical'section on line ,4 a, Fig. 1, through the brush. contact employed in lieu of a f trolley wheel and its supporting bracket, together with a transverse vertical section through the portions of the car frame to which the supporting bracket is secured. Fig. 4 is a fragmentary top plan view of the car frame with the brush supportin r bracket attached thereto and a horizonta section elevated position by single vertical standthrough the brush on line b b, Fig. 3.

In referring to the drawings in detail like numerals designate like parts.

A fragment of an elevated track composed of two parallel rails 1 and 2 is illustrated in vated Figs. 1 and 2 with the rails supported in ards 3 having. bifurcated to elements, to the branches of which the rai s are fastened.

The bifurcated top elements each consist of a transverse member at, having a central socket in which the upper end of the standard is secured and two upwardly extending bent. ends and two vertical side members 5 and 6 having enlarged bases at their lower ends bolted to the upwardly bent ends of the transverse member 4, and inwardly curved upper ends which are bolted to the sides of the rails 1 and 2.

2. and the rails not only serve to support the tact with the channeled under surface of the rails.

The brushes consist of-'a series of sections of wire 14, preterably sl'n'mg piano wire,

and a holder 15 having a metal socket in which the lower terminals of the wire sections are rig-idly secured.

The holler 15 is formed of suitable metal and has an enlarged upper end or head 16 in which the socket for receiving the wire sections is located.

The holder is slidably mounted in a three membercd bracket formed substantially as shown in Figsf3 and 4t, and having upper and lower members 17 and 18 which are secured by bolts or other suitable fastenm s to a member of the car frame, and a lateral v projecting member 19 which is provided,

with a vertical opening and a vertically projccting tubular portlon or flange 20 in which the depending shank of the holder 15 is slidably mounted.

To yieldingly maintain the brush in ele- 'osition a spiral spring 21 is interosed' etween the enlarged head 16 of the iiolder and the member 19 of the bracket, as shown in Fig. 3.

The shank of the holder is secured in the flanged opening in the bracket against removal by a locking pin 22 which is fitted through a transverse opening in the lower projecting end of the shank and extends on opposite sides of the shank sufliciently to catch against the bottom surface of the lateral member 19 of the bracket, as shown in- Fj 3. trips of insulating material-23 are interbrushes to clean the surfaces as the car posed between the supporting brackets and [portion of the bunch or bundle secured the car frame to prevent the electric current passing into the car.

The electric motors are electrically connected to the brushsupporting brackets by.

supporting brackets of which are bolted to opposite sides of the car and maintain the upper extremities of the brushes in the channels .of' the respective rails. -By this means. two sources of electric transmission are employed, and the electric circuit is comthe motor. 5

The wire sections of each brush are arranged in a bunch or bundle with the lower pl'eted through the rails, the two brushes and rigidly in the socket of the holder and the upper portion free to bend or spring under pressure. I

By referring to Fig. 1, it will be noted that the upper terminations of the brushes are forced against the lower surfaces of the rails with sufficient pressure to bend the wire sections of the brushesu This not only insures aperfcct contact but also causes the travels, thereby 'perinanently maintaining a perfect contact; The brushes likewise provide a multiplicity of contacts with a contacting surface of/large area-which minimizes the loss of electric energy in transmission and thus economizes power.

The wheels are insulated from each other 'own nanner; I claim.

"toj prevent short-- circuiting in any well w kn Theconibination with'a bracket, of a enlarged-mead provided wit-h a socket, and

a ser es 'of'sections of spring wire having a holder having a their lower terminals rigidly mounted in the socket of said holder.

2. The combination with a bracket having upper .and lower members. adapted to be fastened to a car, and a lateral projecting member provided with a vertical opening, of a brush composed of a holder having a shank slidably mounted in the vertical opening in the lateral member of the bracket, and an enlarged head provided with a top socket and a series of spring wire sections arranged in a bunch with their lower ends rigidly fastened in the socket of the em larged portion of the holder.

3. The combination with a bracket having a lateral projecting member provided with a vertical opening and a vertical tubular flange above said vertical opening, of a brush composed. of a holder having a shank 'movably mounted in the vertical opening in the lateral member of the bracket, and an enlarged head provided with a top socket, a series of spring wire sections arranged in a bunch with their lower ends rigidly fastened in the socket of the enlarged portion of the end fitted around the vertical tubular flange and its upper end bearing against the-en- I larged headof the brush holde'i. i 4:. The combination with a bracket having a vertical opening, of a brush composed of 4 shank slidably mounted j 1n the vertical opening in the bracket and I an enlarged head provided with a socket, a I series of spring Wire sections arranged in a i bu11ch with their lower ends rigidly fastoned 1n the socket of the enlarged portion of the holder, and a coil spring looselysurrounding the shank of the holder with its respectlve ends bearing against the" bracket and the enlarged head of the holder.
